Izimpawu Zokupholisa Okunephutha Kwe-EGR

Izimpawu

I-EGR Cooler Yemisebenzi Enzima Embi

Ama-coolers we-EGR or Ama-coolers we-EGR I-Он

amadivayisi apholisa amagesi okukhipha amandla futhi asebenze ngokubambisana ne-SCR ukuze anciphise

ukukhishwa kwe-nitrogen oxides (NOx) ezinjinini ezinzima zangaphakathi ezivuthayo.

Inhloso ye-EGR cooler ukusiza ukunciphisa ukukhishwa kwekhabhoni nokuhlangabezana

izindinganiso zamanje ezikhishwa yi-US Environmental Protection Agency. Kodwa

kwenzekani uma i-EGR cooler yakho iqala ukwehluleka? Yiziphi izinkomba

I-EGR epholile engalungile?

Kunezibonakaliso ezintathu eziyinhloko zokuvuza okupholile kwe-EGR:

Intuthu emhlophe. Lapho EGR

i-cooler iqala ukwehluleka, idlulisa isipholile sisuka ku-EGR cooler

ohlelweni lwakho lwe-exhaust. Uma lokhu kwenzeka, i-exhaust ixhumana nayo

lesi siqandisi bese siwuphendula ube ngumhwamuko. Le "ntuthu emhlophe" iphuma

uhlelo lwakho lwe-exhaust lwenjini yakho yomsebenzi osindayo futhi luwuphawu oluqinisekile lwe-EGR

ukwenqaba.

Akukho

okupholisayo kusuka ku-D gas/thangi lakho elichichimayo. Uma igesi yakho ingu-D/ichichima

akukho okupholisayo, kodwa awuboni zimpawu

ukuvuza kwangaphandle (okungukuthi ukuconsa ngaphansi kwemoto) kubi kakhulu

kubonisa ukuthi isipholile sakho se-EGR sinokuvuza kwangaphakathi. Ngenxa yalokho, lokhu

ikhipha okupholisayo ohlelweni lwe-exhaust, okuyinto

kudala amathuba okushisa kwenjini noma kulokhu "mhlophe

bhema".

I-valve ye-EGR engcolile, Iningi

Indlela esebenzayo yokunquma ukuthi i-EGR yakho iyehluleka ukubheka ngokomzimba

Lokhu. Uma ususa i-valve, etholakala phezulu enjinini

eduze kwesihlungi samafutha, kufanele sigcwaliswe ngamadiphozithi ekhabhoni amnyama (umsizi)

leyo ye-exhaust system. Uma une-EGR cooler enephutha,

ikhabhoni eyomile izothathelwa indawo into emnyama efana ne-slime. Lokhu

okubangelwa ukupholisa okushisayo okusabelayo ne-exhaust eshisayo kanye ne-steam fouling

i-valve yakho ye-EGR.
